How can an average retail investor participate in high frequency trading and other Artificial Intelligence trading, or it only for very wealthy individuals? If only for the very wealthy, the market is definitely rigged and manipulated against the small and less-than-wealthy persons this is de facto criminal or at the very least highly immoral and unethical and makes the so-called "market" a travesty. Currently, The market is broken -- witness the "flash crash" to which the market is still vulnerable at any time. The credibility of the market as a "level playing field" has been severely compromised. Please take timely and concrete actions to rectify this situation. Thanks.
